SUEZ provides solutions for the decontamination of soils and restoring of sites polluted by old industrial activities, also contributing to reduce the soil degradation and restoring it.
Thanks to the development of custom solutions, either on- or off-site, with stationary or mobile units, facilities are dismantled and contaminated ground and groundwater are depolluted via thermal, biological, physico-chemical or pyrotechnic processes or containment. All these operations are subject to strict adherence with health and safety conditions and complete traceability.
Former wastelands may then welcome new urban or industrial activities.
The site of the old foundry exploited by the Métaleurop company in the North of France has been decontaminated in this way and reconverted into a multi-process ecopole. Among various activities, a new-generation platform allows 60,000 tonnes of hazardous industrial waste to be treated biologically per year. This waste comes from a number of polluted industrial sites in the region or neighbouring countries.
A renovation project at the Renault site in Boulogne Billancourt, in the Ile-de-France region, consisting of eliminating pollution caused by hydrocarbons or metals, has allowed the sale and reconversion of the land.
The group is currently participating in one of the biggest remediation projects in Europe at the old chemical site of Chesterfields in the United Kingdom. Partly financed by the National Coalfields Program (government organisation for the reconversion of old mining sites), it is the largest public project of its kind in the United Kingdom (98 hectares). Decontamination measures began in September 2009. The reconversion of the site is expected to be finalised in 2014.
